Political map of Australia, New Zealand & the Southwest Pacific 26 July 2003 (Policing the Southwest Pacific): In 1998 Papua New Guinea requested that Australia and New Zealand supervise the peace process in Bougainville, part of a greater trend as the two nations found themselves increasingly involved in maintaining peace in the Southwest Pacific after the withdrawal of Britain and the end of the Cold War (Cold War). In the following years Australia led interventions to help secure the independence of East Timor from Indonesia (International Force for East Timor) and assist in restoring order in the wake of unrest in the Solomons (Regional Assistance Mission to Solomon Islands).
